Hi, Tom -
Thanks so much for your input. Yes, I still use the YP as part of a marketing plan. I usually don't suggest any big dollar investment, unless warranted, just use of your free listing in key areas that make sense, and the basic 'online' listing.
I do believe that the print version is pretty much obsolete (especially because they amaze me at how smal they can make the print - LOL), but for some businesses, mostly those with a business to consumer, in lieu of a business to business target, will still need to include the YP as a part of their normal marketing plan options.
I even believe that you should be using some 'offline' marketing options, even if due to the larger expense, you limit it to 2-3 times per year, simply because many people are now desensitized by Email and traditional Internet marketing options.
I have found that people will hold onto a brochure or postcard I might send, while almost everyone who I Email or reach through Internet marketing, can hit the delete button pretty quickly.
I still get a pretty good return on investment (actually this aspect has improved over the past 3 years, I believe, because most others have transitioned away from this marketing medium and have, like you said, gone almost totally with Internet marketing and utilizing their websites as their only form of marketing strategy.) for several of my offline marketing pieces, and believe it's still a valuable and integral part of my overall marketing plan, and those of my clients for whom I serve as their marketing and social media support partner.
I always suggest that you leave no stone unturned when it comes to determining where you can find your ideal client, and if the YP is able to prove to be a good resource for reaching prosepcts, and not break my budget, why wouldn't I consider it for at least a year, before deciding to remove it from my plan (I usually suggest you give any marketing medium a try for at least 6-months - or 6-8 touches, before deciding to exclude if from a marketing plan)?
Thanks again for your comments - marketing your business in whatever form you decide to use, is best determined by what works best for you. If your business thrives and grows by utilizing only Internet and website marketing, that's where your marketing plan will lead you.
In my position as consultant in the areas of marketing and social media, I believe it's my duty to look at all options available to a client and let the results speak for themselves.
Wishing you all the best of continued success! :)
